The distinction between ribonucleotides (A, C, G, I, T, U) and deoxyribonucleotides (DA, DC, DG, DI, DT, DU) was first made when the PDB was remediated, effective August 1, 2007. The unremediated files can still be obtained, see [[Getting Unremediated PDB Files]]. | The distinction between ribonucleotides (A, C, G, I, T, U) and deoxyribonucleotides (DA, DC, DG, DI, DT, DU) was first made when the PDB was remediated, effective August 1, 2007.
